Joshua ★★★★★

I was worried about getting the right size for a water line repair, but the 70 durometer feels tough and the markings match the dash number exactly. Already finished the job and no leaks so far.

Richard ★★★★★

I’ve been using these for a hydraulic repair, and the 70 durometer feels just right for a snug seal without being too stiff. The -40°F to +250°F range gives me confidence they’ll hold up in my outdoor gear.

Adam W. ★★★★★

These Buna-N o-rings are exactly the 70 durometer I needed for a hydraulic application, and they fit perfectly on the first try. The 35-pack is generous for the price, and the rubber feels durable even at 250°F. I've already ordered another set for spares.
